I currently work as an editor at No Starch Press (http://nostarch.com) where I work on books of all types including Linux, open source, system administration, programming, and general geek interest.
I've been a Linux user since late 1997 or early 1998. I forget exactly when. I didn't become a full time desktop user until 2001, though I used it a lot until that point. Desktop Linux is a particular passion of mine, and I'm a big believer that Linux or some other free software OS will eventually be the dominant desktop OS.
My history with Linux is rather boring. Suffice to say that I didn't really feel comfortable with it until after I had been working at O'Reilly & Associates for several months and had received help learning how to work on the Solaris servers there. With that foundation I started deploying Linux desktops and a print server, and later set up an LTSP server to provide a Linux desktops to the production staff (O'Reilly books are usually laid out in an X11 version of Framemaker running on a Solaris server).
Anyway, as I said, I've been a full-time Linux desktop user for a number of years, I've edited several books on the topic and written a couple of more. Hope you check them out and enjoy them.
